[Brain injuries in relation to morphological structure of dura mater spinalis in pregnant women].

Morphological and histochemical investigations on dura mater spinalis of the lumbar site in 5 women of reproductive age dead from accidents and 5 women dead during deliveries due to hemorrhage were carried out. It was found that one of the etiological factors of head-aches after subarachnoid anesthesia was functional reduction of mechanic and supporting function of dura mater spinalis along with elasticity loss of fibrous tissue, edema and friability. The stable non-healing postpuncture defect of dura mater spinalis resulted in liquorrhea with subsequent development of the "liquorrhea hypotension" syndrome.
